I've used a lot of paintballs, and these Hellfires are close to the best, if not the best I've used.

Marker Setup:

I use a Bob Long Intimidator with an N2 setup.

RecommendedBarrels:

The stock barrel on the intimidator actually worked really well with these balls. But I would recommend getting a new barrel.

Strengths:

They are very accurate. They break on the enemy and not in the barrel. The paint is hard to wipe off, so cheaters won't be a problem. What else can you ask from a paintball? They are specifically made for electro guns (low -pressure), so they work even better with my marker.

Weaknesses:

It's a little more expensive than other balls but you pay for what you get, right? Some other reviews say that the balls quality drops if you let them sit. Name a paintball that doesn't do that? But, these balls can sit for a fair amount of time and still be as good as new. Also, watch out for extreme temperatures and moisture. Yet again, a problem with many other paintballs.

Conclusion:

These balls are an excellent buy, although they are made for electro guns. They are a little more pricey but like I said before, you pay for what you get. These paintballs are currently at the top of my list, and unless I get a different gun that isn't electric (I don't see that happening in the near future), they will stay at the top of my list.
